I used the following code to disable "Rename" Right click context menu in Windows 7  in Autohotkey. But I would like to do the same in Autoit, as am new to it, I don't know, can anyone help. 
 
 #SingleInstance Force
#NoTrayIcon 
#NoEnv
 
MF_BYPOSITION := 0x0400, MF_GRAYED := 0x01
 
Loop {
        WinWait, ahk_class #32770
        WinGetClass, class, A
        If class in Progman,CabinetWClass,ExploreWClass
        {
                SendMessage, 0x01E1
                MenuID := ErrorLevel
